    -- Operations to manipulate Cmvc "Systems".  Each system has some
    -- number of children which may be either subsystems or other
    -- systems.

    -- A system contains "system views".  Each system view contains
    -- an activity called the "release activity" which selects a
    -- released view for each child subsystem of the system.
    -- Thus, a system view describes a complete implementation of the
    -- entire system in much the same way that a load view contains a
    -- complete implementation of a subsystem.

    -- Systems and system views are created by commands in the Cmvc.
    -- Releasing a system view creates a new released system view.
